Ot seems psychological, and if so then I would stop taking any meds for it as these only treat the symptoms and not the cause.

I had suffered from this for many years and tried pills and hypnosis, but these eventually stopped working and I was in a very low place.

I eventually came across a book called Manvice by Kameron Thomas which I could not recommend enough. I will send you the link directly as I don't want to be seen as a spammer.

Basically, it retrains your mind away from worrying about your erection. This really worked as the worry is the cause of the problem. It took a while to do, but the more I embraced the methods, the quicker the problem disappeared for me. What is great, is it is a permanent solution and I have never had a problem since.

Anyway, as said it might be worth checking out so will.post you the link. Best of luck!
